Geomagnetism

http://www.geomag.us/info/mag_field_overview.html

Model and software downloads. The geomagnetic field protects the Earth's atmosphere against charged particles from the solar wind. Rapid and long-term changes in the field are monitored by low-orbiting satellites and a global network of about 200 magnetic observatories. Field models. The primary contributions to the geomagnetic field are. The main field from the Earth's core. Core flow inferred from the secular variation of the magnetic field. The lithospheric field caused by magnetized crustal rocks.

Model and software downloads. DMSP-MAG-1 Magnetic Model of the Earth. The model includes a simple parameterization of the external field, using a spherical harmonic degree 1 expansion of the field aligned with the internal field, and using provided Est and Ist indices to represent the external and induced components of the field. Figure 1: showing improvement of DMSP-MAG-1 in Oersted satellite residuals over the 2010 World Magnetic Model (WMM2010). C library and example driver.
